Figure 4.29 – System > Power Saving
Advanced Power Saving Settings:
Type: Specifies the Power Saving type to be LED Shut-off, Port Shut-off or System Hibernation.
LED Shut-off - The LED Shut-off gets high priority. If the user select LED Shut-off, the profile
function will not take effect. It means the LED cannot be turned on after Time Profile time’s up when
the state is disabled. On the contrary, if the LED is enabled, the Time Profile function will work.
Port Shut-off - The Port Shut-off state has high priority (the priority rule is the same as LED.)
Therefore, if the Port Shut-off sate is already disabled the Time Profile function will not take effect.
System Hibernation - In this mode, switches get most power-saving figures since main chipsets
(both MAC and PHY) are disabled for all ports, and energy required to power the CPU is minimal.
State: Specifies the power saving state to be Enabled or Disabled.
Time Profile 1: Specifies the time profile or None.
Time Profile 2: Specifies the time profile or None.
Port: Specifies the ports to be configure of the Power Saving.
Click Select All configure all ports, or click Clear to uncheck all port. Then click Apply to implement changes
made.
System > IEEE802.3az EEE Settings
The IEEE 802.3 EEE standard defines mechanisms and protocols intended to reduce the energy
consumption of network links during periods of low utilization, by transitioning interfaces into a low-power
state without interrupting the network connection. The transmitted and received sides should be
IEEE802.3az EEE compliance. By default, the 802.3az EEE function is disabled of the switch. Users can
enable this feature by individual port via the IEEE802.3az EEE setting page.
